Breakthroughs in medicine, energy, technology, and industry follow advances in the understanding of materials. Oak Ridge National Laboratory (ORNL) is at the US epicenter for one of the most powerful techniques exploring the nature of materials and energy—neutron scattering. ORNL hosts two of the world’s most powerful sources of neutrons for research: the High Flux Isotope Reactor (HFIR Coherent and Incoherent Scattering of Neutrons The scattering length, b i, depends on the nuclear isotope, spin relative to the neutron & nuclear eigenstate.

Your feedback about lectures and experiments is important for evaluating this year’s Neutron and X-ray Scattering School and for making improvements for future participants. ORNL’s supercomputing program grew from humble beginnings to deliver the most powerful system ever seen. On the way, it has helped researchers deliver practical breakthroughs and new scientific knowledge in climate, materials, nuclear science, and a wide range of other disciplines. Neutron scattering grew from the nuclear science of the Manhattan Project during the 1940s at what is now Oak Ridge National Laboratory (ORNL). Clifford Shull was awarded half of the 1994 Nobel Prize in Physics for research he conducted with the late Ernest Wollan leading to neutron The prototypes were tested on neutron scattering instruments at ORNL’s Spallation Neutron Source and High Flux Isotope Reactor, both DOE User Facilities located at ORNL.
